Stability issues when using Extreme X1 with TP Thunderbolt 3 Dock

Q:Stability issues when using Extreme X1 with TP Thunderbolt 3 Dock

I've been experiencing general stability issues with the ThunderBolt 3 dock. I purchased Extreme X1 for work because of the impressive specs and portability of the device. Overall I've been very pleased with the performance and build quality of the device and Lenovo's software suite makes keeping everything up to date really easy. WIth that said, I've had LOTS of issues with general stability of this product. It appears to Lenovo had issues with the discrete graphics (Nvidia Geforce GTX 1050 ti) which may have mostly been resolved with the latest update. I'm on a fairly recent version of Windows 10 (1803). When using the Thunderbolt 3 dock I still experience lots of issues where the device freezes or becomes unresponsive when docking or undocking. Often times I must force power off the device completely because the device is unable to wake from sleep correctly when docked. I have not tested whether device itself is unable to wake from sleep or if it's just because it is connected from the Dock. However sometimes the device WILL wake correctly but then certain functions will not work, notable USB data will not work often but will be powered (keyboard lights are on but can't use caps lock, for example). Or sometimes the VIDEO won't display at all (thunder bolt graphics issue with discrete GPU) however I can clearly see caps lock works on my keyboard. Note all mentions of keyboard here refer to a USB keyboard wired to the TB dock. Also worth noting often when I come back to the docked computer after a certain period of inactivity, often the device will blue screen (I think this may be resolved with Nvidia update already) or be unresponsive. The unresponsiveness appears to be the USB issue, where USB data stops passing through. Docking and undocking will often resolve this issue but obviously you should NOT have to undock a laptop once docked, this is THE WHOLE POINT OF A DOCK. Now perhaps I'm an idiot but generally speaking not since I work for a consulting technology firm as an engineer. If these issues are this difficult for me I can only imagine how much difficulty the average consumer is having. Keep things simple or people will stop buying your products, whether or not they are engineers. Notes about my configuration:I set BIOS to discrete graphics only. (FYI I think your Vantage team should be aware you cannot get the graphics driver update correctly since Vantage can't tell what the Intel graphics version is when in discrete mode forcing me to choose IGNORE UPDATE if i already i have the update).I installed the Thunderbolt software to manage/see thunderbolt devices. The Dock is authorized already16 GB model with 256 G SSD, 8850H CPU. MAKE IT WORK please!

I keep getting BSOD 'DRIVER_VERIFIER_DMA_VIOLATION' when my thunderbolt dock is connected. I have an X1 Extreme model 20MF-000DUS. I have already installed the following: Thunderbolt Firmware Update Utility for Windows 10 (64-bit) - ThinkPad X1 ExtremeBuild_20180516-N2ETG09W01 Oct 2018Intel Thunderbolt software for Windows 10 (64-bit) - ThinkPad P1, X1 Extreme17.4.77.40015 Aug 2018I started with a Lenovo Thunderbolt 3 dock, but after all the issues despite updating it's Firmware and drivers with the most current:ThinkPad Thunderbolt 3 Driver for Windows 10, 7 (32-bit, 64-bit)V1001317 Sep 2018ThinkPad Thunderbolt 3 Firmware3.12.00320 Dec 2017And I was still having issues with things not being recognized as well as that BSOD so after reading how many people had issues with it despite upgrading firmware and drivers I decided to return it as it would not work properly and go with another dock which recevied stellar reviews as opposed to Lenovo TB3 dock which did not. Now I am using CalDigit TB3 dock and still getting the disconnection and BSOD so I am assuming its thunderbolt drivers, software, or a hardware issue? Anyone else having this problem? Any suggestions? Thank you!

Hi, I am considering to use this dock with X1 Extreme 4K. 1. What is the length of the cable that connects the laptop to the dock?2. Does the dock support rapid charge (80% charge in an hour) of the X1E?3. Is it fully compatible with Linux?

Hello, which Thunderbolt 3 dock is recommended for the X1 Extreme with 4K screen? I plan to connect the following items to the laptop via the dock: 1. A 4K TV running at 60Hz with Chroma 4:4:42. logitech 's Unifying Receiver for the logitech mouse3. a usb 3.1 external ssd4. a soundbar: https://us.creative.com/p/speakers/sound-blasterx-katana5. perhaps something else I also hope that the dock could fast charge the X1E. Thanks.

Hey, I reformatted my Hard Drive today and put Windows XP Professional Service Pack Two on it. I have extreme lag and stability issues which I have never experienced in the past with Windows XP. How could such a thing happen right after reinstalling Windows XP? I can't install applications and sometimes I can't even open something up, because it will just stop responding and my system will crash and I will have to reboot my computer. This happens 5- minutes after I login (if I am very lucky, 5 - 10 minutes). Below is my computer hardware configuration:

I used the Lenovo System Update (v5.07.0074) and was prompted to download and install (was listed as Critical Update) the Firmware to my Dock. As always, I closed all applications and sat as the Firmware downloaded. I got the expected prompt to ensure I was plugged in. I then watched as the upgraded prompted me to install. Installation completed and everything appeared to be fine. I powered down the thinkpad and disconnected. Worked from the living room, then went back to the dock. Connected, and noticed that before I connected the White light on the power button was illuminated. Shrugged, and pushed the power button. Nothing. I un-plugged the Dock, got a cup of coffee, returned and plugged it back in. Nothing. I then noticed that none of the pass-through power was working on the dock. So, I unplugged it again. Unplugged everything connected to it, and held the power button down for 15 seconds in an effort. All of this at the recommendation of Lenovo Support. Who, by the way, was very nice and well spoken. Nothing we did worked. I happened to have another Thunderbolt 3 cable in my bag, and no change. I powered up my new X1 Yoga, and connected the cable. No power. This wasn't passing power at all. I confirmed the Intel Thunderbolt app was running, and confirmed that Windows was not even detecting the Dock. Lenovo is sending me a replacement. I had this one all of a week. Did I miss any other steps while I wait for it to be repl... Read more

Hey There We have bought 15 Studio G3s and docks to go with them We have ran into issues with about 40% of the docks. Not sure if its the docks or laptops causing the issues. One laptop tries 3 diffrent docks, USB and Ethernet wont work. Another laptop will randomly BSOD, if the dock is even touched it will BSOD as well. I've gone though all the posts about these issues from last summer but nothing really seems to help. Is there a newer fix that I am missing somewhere? Thanks Josh

Hi There, I'm having trouble with a Lenovo P52 with a Thinkpad Thunderbold 3 Dock. When I Conect my dock to my laptop it wil ask if i want to allow it. (It always asks strangely. Even if its in managed Thunderbolt devices.) After pressing ok the problems start.-Shortcuts are flickering on the Desktop and in the taskbar.-Not being charged-No Mouse & Keybourd-No Ethernet.-External screen does work but with above problems. Additional information:-With only the powercord and usb-c into the Lenovo Laptop and nothing else in the dock it stil gives the same problems.-Tried with difirent cables.-Tried other Docks but same problem. (Docks that work with other Lenovo laptops)-It works somtimes. once every 5-10 tries. But fail right after trying again.-No Faults in Lenovo center. Product information:Lenovo Vantage InfoLenovo Thinkpad Thunderbold 3 DockModel Number: DBB9003L1 I have updated the most drivers that would be needed for the thunderbolt & Lenovo but nothing seems to work. Is there anyone who has been batling this before or somone who could help me?

Issue 1I purchased the ZBook Studio G3 + 2 months wait on the Thunderbolt 3 Dock to primarily connect 2 4K Samsung monitors. When connected via the display port one will display at 4k while the other will only display @ 2560X1440. I had bought a a couple of CableMatters thunderbolt 3 X display port adapters while waiting on the dock. If I plug one of the monitors in using the adapter and the other into the display port both will display 4K.Anybody else having this issue? Issue 2After the computer goes to sleep only one monitor will wake up. The NVDIA control panel still shows both connected. Only way to get the second monitor awake is to shutdown and reboot. Issue 3I have the displays configured to go blank after 1 hour. Once this occurs and I enter my password all of my open programs are displayed on one screen rather than on both. This would be normal if you have undocked and re-docked a laptop. Issue 4If the laptop is opened while docked. One display goes blank and one is duplicated with the laptop screen. This is not typical docked behavior. I moved from an Elitebook 8540W with dock. I'm really questioning my whether this was an upgrade.

We received a new 5510 laptop that works great on its own, but when adding in the thunderbolt dock we experience odd issues

1. If the laptop lid is closed while connected to thunderbolt, the laptop will hang at the Dell bios screen. If the lid is open while power turned on, the laptop boots up fine. However, the BIOS screen is still not visible on the external monitors, only when the OS has loaded2. Dell shipped a new dock which had no differnce, and then I uninstalled every single driver and downloaded/installed in order from Dell's website, including updated Thunderbolt firmware and BIOs

The laptop is running Windows 10 x64

2 things I have noticed:1. In device manager, the Thunderbolt Controller 1575 is hidden. Viewing hidden devices and opening this controller states:"Currently, this hardware device is not connected to the computer (Code 45)" The resources tab states that there is a problem with the deviceOf course, reconnecting makes no difference. I have also unplugged all peripherals from the dock to make sure there was not a conflictSecond, in device manager, there is no listing (visible or invisible) for ASMedia USB 3.0 Extended Host Controller Driver for Dell Thunderbolt Dock, regardless of uninstalling it through Add/Remove Programs and re-installing.One more note - I am able to work normally after booting with the lid open successfully and then closing the lid.

A:Precision 5510 issues with Thunderbolt dock

I have the exact same symptoms with the same hardware (precision 5510 & WD15). the computer will not POST when it is either started or restarted with the built-in display closed. If the lid is open... all is fine. Ohh.. and when you do try to start/restart with the lid closed, i get a 2 orange, 7 white blink code. it will continue to repeat this until I open the lid and press the power button. This will then cause the unit to successfully POST and boot up.I'm running Windows 8.1, and have installed all available dell updates as of March 28th, 2016

Hi all, I do tech support at a university that uses various Lenovo notebooks across campus. I have noticed a trend among the users that have a Thinkpad Yoga 370 Notebook and are using a Thinkpad Thunderbolt 3 Dock, myself included. Occasionally (every few weeks or so), one of the affected systems will show "plugged in, not charging" tooltip when hovering over the battery tray icon. When this happens, the charge indicator light by the charging port and Thunderbolt port does not turn on, the battery continues to drain, and unplugging the Thunderbolt cable and either plugging it (or the regular power cable) back into the notebook has no effect. These systems all use Lenovo System Update to keep their drivers and BIOS up to date, and I have updated the firmware on the Thunderbolt 3 Docks manually. This issue was brought to my attention because it started happening to me and my laptop/dock after the first few weeks of having it, and this behavior continued to happen for months. I would constantly be plugging in and unplugging my laptop, as I do on-site support in several buildings, and my laptop goes everywhere with me. In October I stopped using my dock entirely, and since then have had 0 problems when just using the laptop's regular charging cable. I have 3 or 4 other users whom I support that have this issue though; due to the sheer volume of documents they need open at once, they need a multi-monitor setup and ethernet ports, so not having a dock is not an option.

I am using a Jabra UC Voice 550 Duo USB headset (Skype model) with Windows 7, for business communication. Or, at least, that was the intent: The reality is that if I use any ports on the docking station, I lose connectivity in the middle of a call. Several Skype chats started out okay, and then the microphone on my end simply stopped working (I could still hear the other party.) Also playing audio (Youtube via Google Chrome) has also resulted in eventual loss of playback. I have had to plug the USB headset directly into the laptop, in order to obtain glitch-free audio (via the on-board Intel USB root hub). The ASMedia USB root hub in the Thunderbolt docking station seems to be the culprit: I have two HP Z24n monitors plugged in via DisplayPort, and it makes no difference if I use USB ports on the monitor vs. directly plugging the headset into the Thunderbolt docking station itself. Since the laptop has limited USB ports, I would like a solution to this problem, please. The ASMedia root hub is running on driver version 1.16.33.1, dated 04.02.2016. One last thing: I got driver software for my Z24n monitors on CD-ROM, but hardly any notebooks are shipped with CD/DVD drives these days - and I could not find an online copy of the software, so I could install the display profiles.

I have three ZBook 17 G3 that I cannot get a Thunderbolt dock installed correctly on. The first does not seem to want to install the thunderbolt driver, so that one's fun. The other two are having a different issue entirely. I have read multiple threads here about similar issues, and none have offered a solution for my situation.I have tried the latest BIOS, I have tried an older BIOS, I have downloaded the drivers and firmware(which won't install because it doesn't detect the dock) Whenever I plug the dock in, Windows installs the drevices, but gets stuck and winds up with a "Base System Device" that it cannot find a driver for. I have tried three different docks, and three different cables. All have the exact same result. Is there an obscure driver that I need to download to install that is not obvious in all of my searching? Any questions or clarifications, I'm happy to respond. -Keith

I just got a new Carbon X1 6th generation (20KG). I started using this with my Thunderbolt 3 dock (40AC), that I successfully used with my previous Carbon X1 5th Generation. There seems to be some compatibility issues here. After using it with the docking a while (apprx. 1 hour), the X1 suddenly started to continuously disconnect/reconnect from the dock (each 2-3 seconds), before it permanently was disconnected from the docking and would not connect at all. When I disconnected the X1 from the dock and restarted (without connecting to dock) the X1 Thunderbolt software and devices/drivers related to that on the X1 "went crazy" and appeared/disappeared from the device manager continuously (each 2-3 seconds). I needed to enter bios and temporarily disable internal battery for it to normalize again. If I then connected to dock, the same would happen after some time. I've updated Thunderbolt software, drivers, firmware and also Thunderbolt 3 dock firmware and drivers, so no more to do there. I have not verified it completely yet, but it might be that the disconnect/crazy_stuff happens when the battery charge of the X1 reaches 100%. I once connected the X1 to the dock when the charge was 97% and it was stable then (the X1 does not charge on AC when the battery is > 95%). If this is the reason, one solution might then be to use Lenovo Vantage to set max charge to e.g. 97%, but I think this is a poor solution. Some ... Read more

We purchased a new X1 Carbon 6th Gen with the new Thunderbolt 3 Dock Win 10 1803 and have had all kinds of problems. Bad enough to consider other brand alternatives. All Lenovo drivers are current, we updated the firmware and drivers for the dock. With that we still have the following problems and dont know how to resolve them1. The network connectivity from the dock to laptop with USB-C loses connectivity on occasion. Also when the user shuts off the laptop, comes back and turns the laptop on, no network connectivity is re-established. The only way to fix this is to unplug the USB-C cable and plug it back in. Sometimes that will lock up windows and we have to do a hard shut down and start of the laptop. 2. Running the display out from the dock is not always reliable. The monitor will turn off randomly. To bypass this issue we have to just plug the monitor directly into the laptop. 4. Occasional random bluescreens with a stop code DRIVER_VERIFIER_DMA_VIOLATION. This error is related to bad drivers.Are we missing something. Is there anything we have to set in the BIOS to resolve these problems? I've been reading up on this dock and a lot of people are having problems with this dock and carbon 6th gen laptops

We have a Dell Precision 5520 that uses a TB16 docking station that all of a sudden is having difficulties connecting to our VPN. It was fine earlier in the day. We tried clearing the DNS cache and tried a winsock reset. THe drivers are up to date and everything. Also tried to reboot the computer multiple times.Even tried a K17A Dock and had the same issue.We were finally able to get the computer to connect to the vpn once we used a usb net adapter to plug the ethernet cable into.Tried plugging the usb adapter into the computer directly and into the dock. It worked whether it was directly connected to the computer or the dock.It only does not work when we connect the ethernet cable to into the lan port on the TB16 and K17A dock. And only for the one computer.

We have about 400 Lenovo T470s laptops running Windows 10 and many are having issues with recognizing the external keyboard and mouse when redocking or turning on in the morning using the Lenovo Thunderbolt 3 Dock. We have done the following: Run System Update to get the latest driversRan firmware update on the thunderbolt 3 dockUpdated Windows to 1803 and ran system update again.Changed following BIOS settingsWake by Thunderbot (TM) 3 - EnabledSecurity Level - No SecuritySupport in Pre Boot EnvironmentThunderbolt(TM) device - EnabledUSB device - Enabled What can I be missing? This should not be happening. This is the first time that we have used a non-mechanical dock. Please help!

Got a sealed refurb from Lenovo, Thinkpad X1 Extreme 20MF000DUS.Updated everything from Lenovo + Windows (including BIOS to 1.18 )I have an external USB-C gen2 monitor (single cable for Video+power) Works absolutely great on older Yoga... On this X1 Extreme machine it would sometimes work, but 80% of the time would not. Monitor gets power, but no signal.It would also spit out error of USB device not recognized and this in device manager:Windows has stopped this device because it has reported problems. (Code 43)A USB port reset request failed. Also, sometimes it would show this in device manager under UCSI USB controller when monitor is plugged: Windows has stopped this device because it had reported problems (code 43) External USB-C hard drive works... on Thunderbolt. The long list of things I have tried to make monitor work:Uninstalling usb drivers / rebooting machine.Trying both Thunderbolt portsTrying a different cableRunning Vantage diagnosticManually installing latest chipset driverDisabling security for Thunderbolt in BIOSSetting a power plan for maximum performanceDisabling power savings in USB portsTalking to absolutely ridiculous Thinkpad for nearly 2 hours without even trying to troubleshoot my problem. What I found a bit strange:There are no dedicated (separate) USB drivers on Lenovo support page for my laptop. The USB driver dates are 2006 in device manager... I do not believe there were any USB-C laptops 12 years ago... Ca... Read more

Hi Folks.I have X1 Extreme laptop. Trying to connect USB-C (gen 2) monitor, does not work properly.When I plug hard drive to Thunderbolt port, it shows up in "My computer" and is accessible, but it does not show as a device in Lenovo Thunderbolt software that came with machine... It shows "ports", but no devices... Can somebody please tell me if it (attached devices to Thunderbolt) should show up there.Please see attached. Trying to figure out if my monitor has compatibility issues or just flaky TB3 controller. I thank you in advance.

Both PSREFs claims [email protected] over Thunderbolt but I thought the dual port controller (even in Alpine Ridge and I suspect these will be Titan Ridge) always had eight lanes of DisplayPort fed into it which is enough for 5K @ 60Hz. So what gives?

I recently purchased a X1 Extreme and was hoping for plug and play eGPU via thunderbolt 3. However, the Akitio Node (+ 1080 ti) does not even power on when I connect the thunderbolt 3 cable to the port. Both the Lenovo Vantage + Windows Update states my firmware + drivers are up to date.

HP ZBook Dock with Thunderbolt 3 usb device issues. USB Keyboard randomly sends a stream of a repeated character. I will be typing and mid worrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr d will get results like in the word above. The inverse happens alot too, were it just drops a few characters i have typed. USB Mouse lag is horrible. Both devices will stop functioning, need to reboot the dock to recover them. Any one have any suggestions or which drivers are the most stable?

#HPExpertDayYou will have to update BIOS/Firmware if any. Install the docking station drivers. Try using a different keyboard, if the issue stops then issue was with keyboard.http://support.hp.com/us-en/document/bph07165

$3k laptop, thunderbolt doesnt work and try to upgrade firmware gave me error that there is no controller, have been working on setting this laptop up for two days. Changed bios graphics to discrete (latest bios version) BIG MISTAKE now it won't boot AT ALL, not even to get into bios. It seems they didn't do any testing. On hold now for support for 30 min and counting .....

I'm unable to connect my Apple Thunderbolt Display to my new Thinkpad X1 Extreme. I have an Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter, and it works with our other Thunderbolt 3 capable laptops (MacBook Pro and Dell XPS 9560), but nothing happens when I connect it to the thunderbolt ports on my X1E. I have upgraded all bios and drivers to their latest version, From the About-box on the thunderbolt software:Software package version: 17.4.77.400Application version: 17.4.77.10Service version: 17.4.77.6Controller driver version: 17.4.77.13NVM Firmware version: 36.00

I have a new P51, 64 GB ram, SSD hard drive. Ihave a docking station at work and one at home. The one at home has a 6 TB Seagate BarraCuda pro USB3 drive attached. When I dock the laptop at home, the system will not boot. It gets to the bios boot sceen and stays there until I turn off or disconnect the USB drive. Once I do that, it continues to boot and if I turn the USB drive back on, it works fine. If the drive is my old 1 TB barracuda, it boots normally.

I want to buy the Lenovo Yoga 920 (i7 with 16 GB) and I?m used to work with 3 external full HD Monitors. Since it has 2 Thunderbolt ports, it looks like the Thunderbolt 3 Dock may work with the 920. However, it is not listed on the compability list for the dock. Therefore: are the dock and the 920 working together?

Is the new ThinkPad Thunderbolt 3 Dock compatible with P50? Dock details page (https://pcsupport.lenovo.com/cz/en/solutions/acc100356) only list P51s, but not P50. But P50 claims support for Thunderbold 3. If yes, can I connect Ethernet LAN over the dock? And what driver I need to install?

I connected my P1 to my existing Thunderbolt 3 dock and to my pleasant surprise, the system was in charging mode when the system was off. I thought that the unit could only charge through the slim power connector port, but it seems that it will also charge through the Thunderbolt 3 port when the system is not running.

Hi I have 2 new L480 (20LS-001AMX) and 2 new Thrunderbolt 3 Dock (DBB9003L1)Is there some way to get this type of dock to work with the L480? Note: in the Dock spec. the L480 are not mentioned are compatible.Could it work any way? Mikkel

Love the concept of the thunderbolt 3 dock, can't fathom how it was designed though. On my zBook 15 G3, the power and thunderbolt ports are on the right side of the laptop. The dock has the cable port on the left rear side, completely crossing over all the ports when you put the dock on a desk with the back facing away from you. Then they ship a cable that is barely long enough to put the dock directly behind the laptop and connect it. Where do I buy a longer cable HP, please!

As the only docking solution available and moving from a more traditional dock, its less than suitable. HP needs to make a longer cable and the end that connects to the laptop should be at a right angle. The cable is so stiff and thick it takes nearly 4" to make the turn. HP makes it impossible to find this out how long the cable is with out purchasing and at that point your stuck with it. Hardly a customer satisfaction issue they should want to propigate!

I have a new ZBook G3 17" with ThunderBolt 3 dock station.I have install my laptop with boot up finger&password protection.I have connect display, keyboard and mouse to this dock.Every time I bootup, I have to open laptop to insert access data.This look like a stupid solution compare the old HP docking station that I have on my HP 8760W where dockingstation are working from first second and I can insert my access data (password) without opening lid.There are any solution to this problem ?I have also another problem. On the old PC was possible create a protected area of HD using a little part of it withHP ProtectTools. This SW is not possible to install on ZBook G3.I don't found any solution to create it. Only using Windows 10 (that I don't want to use) functionality.More we go on and worst SW/HW are delivery to user. AC

Hi,I have a Thinkpad P50 and today my Dell Thunderbolt Dock arrived.Unfortunately, it doesn't work (= it is not recognized in any way), although Dell specifically says that the dock also works with non-Dell Thunderbolt 3 machines. I have installed the Thunderbolt software from the P50's driver site and updated to BIOS 1.17.Lenovo released an "Intel Alpine Ridge Thunderbolt Firmware" for the P70. But there's no such firmware update on the P50's site, just the Intel Thunderbolt Software from November.The 1.17 UEFI/BIOS Update says it fixed a Thunderbolt issue, but apparently not mine Has anyone ever gotten some Thunderbolt 3 device working on the P50? I just hope this will be fixed soon, because the Thunderbolt dock seems to be the only convenient way to drive three 4K displays with the P50 (2 via Thunderbolt 3, 1 via miniDP).

We recently started using Bitlocker with a PIN at startup. On all our laptops using the "old"-type dock, that you click your laptop into everything is working fine, the users put the laptops into the dock, turn it on, type in the Bitlocker PIN using the external monitor and keyboard, and then processed into Windows. Our problem is with everyone using the new Lenovo ThinkPad Thunderbolt 3 Dock. When the users connect the laptops to the dock using the cable and then power on from the dock, the laptop will power on (the LED in the ThinkPad logo lights up) but the monitors and keyboard connected to the dock is not working, and then after some time the laptop will power off again. We currently use a workaround where the users power on, type in the Bitlocker PIN and login to Windows before connecting the laptop to the dock, but this not a proper solution. We have Enabled both "Thunderbolt(TM) device" and "USB device" under "Support in Pre Boot Environment" in the "Thunderbolt 3"-menu in BIOS, but it still doesn't work. Have anyone else experienced this problem? Or does anyone know of a proper solution.

I have a Yoga 370 (Win10) and a Thunderbolt 3 dock & Thinkpad USB-C dock and i cannot get them to play nice. I am using the USB-C cord on both devices, it transmits video and power but not USB or Ethernet. I have downloaded drivers and firmware from Lenovo and still no luck, the computer does not see the dock BUT the video and power are there. I changed my BIOS settings per the firm ware update well and no luck. any help would be much appreciated!

https://support.lenovo.com/us/en/solutions/acc100356 Hello I have the new X1 carbon laptop (5th gen). I also have two 24 in thinkview external monitors with hdmi/display port inputs. If I buy the above adapter will I be able to run the two external monitors in extended mode so I have can have three different screens total (laptop screen, monitor_1, monitor_2)?

So I have an X1 Carbon Gen 5 (Kaby Lake) and the Thunderbolt 3 Dock Gen 1 (40AC0135US). I bought two 4k monitors and after several frustrating hours figured out that the Gen 1 dock can't output 4k on two externail monitors at 60hz, this appears to be a dock limitaion only. I see that you now have a Gen 2 dock (40AN0135US) that says it will do 2x 4k @ 60hz, only problem is that every compatability cross refrence I can find does not say the gen 5 X1 Carbon supports this new dock. I don't see a good reason for it not to be compatiable, but wanted to find out for sure one way or the other before I bought it, as it is not cheap.

So I have a Precision 5510 laptop with Xeon processor, no 4K screen. My question is about this thunderbolt dock TB16. I have one HDMI out and was asked if I can make that work on 3 external monitors. None are 4K. Is that possible? Can it function as extended desktop, not duplicated? And if so, is that 3 external plus laptop? Or is the laptop screen on of the 3?

Hello all,I bought a Yoga X1 2018 and during the shop they suggest the Lenovo Thunderbolt 3 Dock. Since I thought that having to disconnect only one cable when bringin the laptop from the desk to the meeting room would have been useful, I bought it.With my disappointment I setup everything and I did some tests on the laptop just to discover that the performance of the laptop when powered through the docking station are 1/3 with respect to when it's powered by the 65W power supply and 1/2 of when the laptop is on battery... (234pt vs 640pt vs 563pt | dock/65W/battery)Now since the docking station has a 135W power supply, I really can't think that this is an issue with the supply from the docking. Also since the laptop is even faster on battery I really don't understand how it could be related to the power supply... anyway I've connected both the 65W power supply and the docking and the performance are back to normal.Is there anyone who can suggest me what's going on or how to report this to Lenovo?

Hello,i have the same setup (X1 Yoga 3rd Gen + Thunderbolt Dock) and dont experience less or different performance.I have 2 monitors with display port and couple of USB devices connected to the Dock. Also using 2 external and the Yoga monitor at the same time was never a problem.What tests have you done to measure the performance?best regards,AT

I just picked up the TB3 dock and all seems to be working, however it is not charging my laptop using the included Thunderbolt/Power combo cable. The power light shows on the dock, and connected devices work on laptop, but no power. Any ideas?

For some reason, i can't turn on my new P51 using the power button on the Thunderbolt 3 dock. I'm sure i've got something hooked up wrong, but thought i'd check here. Is there a setting in Control Panel (power button) that i need to change? In order to use my laptop / view from my external monitor, i have to open the lid to the laptop, power on and then i can use the external monitor. thanks for any help.
